AS many as 4,000 households in Dublin will experience low water pressure or no supply until Sunday due to a break on a large distribution mains.

Dublin City Council said homes in Cabra, Glasnevin, Phibsboro, Drumcondra, parts of Donnycarney, Santry and parts of Beaumont on the northside would be affected.

Homes in the Heuston area south to Thomas Street and east to Bridgefoot Street will also be affected.

The council said the break in the mains would result in reduced pressures, and the possibility of temporary water loss.

Work on the repairs began at 6.30am today, and are likely to continue into Sunday evening.

“There’s a 1000mm water main that feeds into the northside of the city and the break has occurred near the Guinness Hopstore,” city engineer Michael Phillips told independent.ie.

“It’s about four metres down and we will be excavating on it tonight. We cannot work through the night because of health and safety reasons.

“We would hope it will be low pressure, but with peak demand people may lose pressure. There would be about 3,000 or 4,000 houses affected.”

If required, water tankers will be made available for customers. Locations of tankers will be detailed in updates throughout the weekend, through press releases, on the council’s website at www.dublincity.ie and on Twitter @DubCityCouncil.

The council apologised for the inconvenience caused, and asked homeowners to conserve supplies.

Customers experiencing severe water disruption should contact the water services division’s emergency number at 01 6796186, outside of office hours.
